Matsya Purana — Solar Dynasty Prelude: Vivasvān–Saṃjñā–Chāyā
सवर्णत्वाच्च सावर्णिर् मनोर्वैवस्वतस्य च ततः शनिं च तपतीं विष्टिं चैव क्रमेण तु //
savarṇatvācca sāvarṇir manorvaivasvatasya ca tataḥ śaniṃ ca tapatīṃ viṣṭiṃ caiva krameṇa tu //
Because he was of the same lineage and class (savarṇa), in the line of Vaivasvata Manu he was known as Sāvarṇi; and from him, in due order, were born Śani, Tapatī, and Viṣṭi.
This verse does not describe Pralaya; it functions as a genealogical link within the Vaivasvata-Manvantara narrative, listing descendants in sequence.
Indirectly, it supports the Purāṇic framework that grounds dharma in lineage and succession—establishing who inherits royal and social responsibilities through an ordered dynastic chain.
No Vāstu, temple-building, or ritual procedure is stated in this verse; its significance is primarily genealogical (dynasty and succession).
